'Super-TB' created by scientists

A.S | 26.12.2003 09:40

Yeah ain't it great a new super TB by accident imagine what these shit heads can do when they really put their minds to it . new funky strains of AIDS and SMALL POX as required by NWO ....
With Nazis like Bayer looking after our GM foods , sure they can earn a few bucks on the side creating super strains of deadly viruses and plagues ..

'Super-TB' created by scientists



TB is a major world killer
A virulent form of tuberculosis was created in the laboratory by experts trying to alter its genetic structure.
The mutant form of the bug multiplied more quickly, and was more lethal than its natural counterpart.
Researchers from the University of California at Berkeley had actually been trying to disable genes and make the bacterium less deadly.

"This is one of the very few hypervirulent organisms ever created," said scientist Dr Lisa Morici.
Tuberculosis is one of the world's biggest killers, and scientists are probing its genetic structure in a bid to find weaknesses that might be exploited by new treatments. the Berkeley study, published in the Proceedings of the National Academy of Sciences, concentrated on a particular collection of genes thought to give TB some of its virulence - its ability to infect.

Growing threat

They disabled these genes, and expected to find a weakened form of TB as a result. Instead, the organism grew in virulence.

It killed laboratory mice within seven months of exposure, while those infected with normal TB survived the experiment.

Further investigations suggested that the genetic changes had the unexpected effect of undermining the body's own immune response against TB.

Professor Lee Riley, who led the study, said: "These findings came as a complete surprise to us.

"We thought we had made a mistake, so we repeated the test several times, and we always got the same result."

Bioterror played down

There have been fears that similar genetic modifications might lead to a new form of TB that could be used in bioterrorism, but Dr Morici said this was unlikely.

The bacterium is hard to deliver in an aerosol - the accepted method of spreading it over large populations, and despite its extra virulence in the lab, still grows relatively slowly and can be treated by antibiotics.

"There are several other organisms out there that are easier to manipulate than TB," she said.

Dr Neil Stoker, from the Royal Veterinary College at the University of London, said that his research had also uncovered "hyper-virulent" strains of TB.

The emergence of these strains should pose no risk to humans, he said.

"These are not going to become 'super-strains'," he said.

"They are already going to be out there, and they have not become dominant."

TB is such a "successful" pathogen, he said, for completely the opposite reason.

"It is such a phenomenal pathogen because it does not cause disease in everyone it infects.

"It has this extraordinary ability to transmit itself, and nine out of ten people who have it will never fall ill."
